The Trelino® Origin M is only about a hand breadth higher than a beer crate and similarly compact.

Number One (Pee)
The urine canister has a volume of 1.3 US gal and holds 9 - 11 No. 1s.

Number Two (Poo)
The solids container has a volume of 1.8 US gal and holds 5 - 10 poos.

At 13.7 lb the Trelino® Origin M is easy to transport.

Area of application
With its compact dimensions, the Trelino® Origin M feels particularly at home in the Sprinter van, truck camper, RV or on the boat.

Odor neutrality
The separation and drying function of the toilet prevents unpleasant smells.

By dispensing with chemicals and water, the Trelino® Origin M is environmentally friendly and preserves natural resources.

Without water and chemicals, the Trelino® Origin M offers the freedom to travel independently of disposal stations.

Hygiene and cleanliness
Individually removable containers allow separate emptying and easy cleaning.

Leakage safety
Due to the solid workmanship, the exterior is leak-proof and protects against unpleasant mishaps on the road.

Water resistance
The exterior made of polyethylene is water resistant and therefore can also be used in the shower.

With its high-quality, robust body, the Trelino® Origin M takes on any adventure.

A fan can be installed for even faster drying of the solids. The hole in the separation toilet for the fan must be drilled yourself. We recommend a step drill 1.53 inches.

The body and containers of the Trelino® Origin M are made of recyclable, acid and chemical resistant polyethylene (PE). The waterproof glued lid is made of multilayer, untreated birch wood.

Lid attachment
The lid is fixed by holding magnets, which ensure that the separation toilet always remains well closed.

With its stylish wooden lid and shapely curves, the Trelino® Origin M will turn your smallest room into something very special.

Regional production
Production is carried out exclusively in Germany, taking into account high social standards.

How does a composting toilet work?

The inner workings of a composting toilet essentially consist of three parts: separator, urine canister and solids container. The separator leads the urine into the canister, while the solids end up in a bucket with a compost bag. You can also read a more detailed version in our blog post here.

What should I pay attention to when using it?

The correct sitting position is crucial for the best possible function of a composting toilet. For anatomical reasons, this differs for women and men. 

Why does a composting toilet not smell?

Odors are caused by the mixing of solids and liquids. Separating the excreta and then drying the solids prevents undesirable aromas. 

Do I have to change/empty the plastic bag after each use?

No! The whole point of using litter as a cover material to dry out the poo is that you can use the bag for several days and only empty it once full enough. Depending on the size, the bags hold between 3 and 12 number 2s.

Where can I get the litter / cover material to dry the solids?

You will be able to buy litter from us some time early next year. Until then or otherwise you can also buy good litter material from any garden or home improvement store. Find more info on our blog post about litter here.

When do I need a fan?

A fan counteracts condensation, accelerates the drying process of the solids and ensures that fragrances quickly dissolve into thin air. This makes it particularly suitable for long emptying cycles or if your Trelino® is used by several people. All Trelino® models of sizes M and L can be equipped with an optional fan. Any S model does not need a fan due to its compact dimensions and short emptying cycles. 

What happens when I have diarrhea?

Diarrhea is not a problem when using a composting toilet. Just use more litter to compensate for the liquid.

Where do I dispose of the contents?

Urine can easily be disposed of in a toilet connected to the sewer system. Diluted, it is also suitable as fertilizer for the home garden or the raised bed on the balcony. The bag with the solids is a case for the residual waste garbage can. Conditionally, composting is also possible. The urine canister and solids container can be emptied independently of each other.

Plastic bags and composting - how do they fit together?

For us, sustainability and environmental awareness do not end with disposal - we think beyond the garbage can. That's why we use renewable, organic materials for our solid bags that can be easily composted.

How do I clean a composting toilet?

Cleaning a composting toilet is as simple as its use. The household remedy diluted vinegar concentrate has proven its worth for most of the cleaning. Read more about it in our blog post here.

What makes Trelino® so special?

Trelino® is a quality product designed to last. A high-quality composting toilet that will accompany you for many years and makes a statement against the throwaway culture. In addition, Trelino® combines optimal functionality, ease of use and high comfort behind a unique design.

Amazing toilet

We were so impressed with the toilet, and the lack of smell and the easiness to empty and maintain that we plan on buying the large one when it becomes available. The medium one is just a little too small for us and our needs but we are going to continue to use it in our other trailer. Highly recommend this toilet to anyone camping in a van or even replacing in a trailer.

Brenda B. (Canada)

Even better than I thought!!

Rodney B. (United States)

Couldn’t be happier with your product and has greatly improved my daughters experience with road trips in the van.

Expensive but I love it

We started with a porta-potty, but after purchasing it quickly realized that brand would be a disaster waiting to happen. After extensive online research, we discovered Trelino and though pricy, it is the easiest, cleanest and best portable toilet out there. It is cleverly designed, keeps solids and liquids separate and could not be easier to use and maintain. I cannot recommend this highly enough. Its a game changer....I will never use a pit toilet again!
